Answer:
t = 39
Step-by-step explanation:
the diagonals of a parallelogram bisect each other, therefore t = 3t - 78 further solving this equation we get
2t = 78 and then t = 39
Answer:
At end of summer, the Maple is 19.44 feet
Step-by-step explanation:
We need to find 8% of 18 feet and add it to 18 to get the new height.
To get percentage to decimal, we need to divide by 100. Hence
8/100 = 0.08
8% of 18 is:
18 * 0.08 = 1.44 feet
Now, we need to add this to 18 feet. We have:
18 + 1.44 = 19.44 feet
Answer:
no solution
Step-by-step explanation:
heres why:
Let's solve your equation step-by-step.
4x−9(x+1)=20−5x
Step 1: Simplify both sides of the equation.
4x−9(x+1)=20−5x
4x+(−9)(x)+(−9)(1)=20+−5x(Distribute)
4x+−9x+−9=20+−5x
(4x+−9x)+(−9)=−5x+20(Combine Like Terms)
−5x+−9=−5x+20
−5x−9=−5x+20
Step 2: Add 5x to both sides.
−5x−9+5x=−5x+20+5x
−9=20
Step 3: Add 9 to both sides.
−9+9=20+9
0=29
so there are no solution
